Click 17 year old female with a dermoid cyst in the left side of oral cavity.
Findings: Gray Scale Ultrasound images in short axis demonstrate a well-defined, lobulated echogenic mass along with hypoechoic areas interspersed in between.
Technique: Gray Scale Ultrasound images in short axis.


Click 17 year old female with a dermoid cyst in the left side of oral cavity.

Click 17 year old female with a dermoid cyst in the left side of oral cavity.
Findings: Note an ovoid lesion at the floor of the oral cavity on the left side within the sublingual space. Lesion measures 4.0 x 3.0 x 1.5 cm. There are areas of negative Houndsfield units (-30 to -20 HU) within the mass suggesting a fat component. No osseous erosion or destruction of the adjacent mandible is noted. No extension into the submandibular space is seen. There is mild expansion of the inferior aspect of the lesion, which displaces the mylohyoid muscle inferiorly. There is no enhancement with contrast.
Technique: Axial CT, 150mAs, 120kV, 3 mm slice thickness, 80 ml Iohexol contrast injected iv
